Eisenmenger syndrome is a disease caused by a septal defect, or hole in the heart. As the condition progresses, fresh and deoxygenated blood begin to mix, with the latter seeping through to the body, causing pressure to build in the lungs and stretching the lung tissue. In the U.S., the defect is usually closed up right away, but in the developing world children often grow up with the hole. Until now, the solution was a heart/lung transplant, which...
...Times was comically eager to point out that other ethnic groups probably have a lesser genetic tendency to a larger number of diseases, so Ashkenazi Jews shouldn't feel that put upon. Nevertheless, both stories raised the possibility that blood tests for this genetic defect will be used by health insurers and employers to discriminate against people with the defective gene. (Why? Oh, possibly bosses may not want their workplace atmosphere soured by a lot of grumpy people who've just undergone a colonoscopy...
...YOUR EYES Opening new avenues of research, scientists have identified a gene defect associated with age-related macular degeneration, the leading cause of vision loss in people over...
KNOW THY GENES Researchers have found a genetic defect present in roughly 6% of Ashkenazi Jews that doubles the risk of colon cancer. The mutation can be picked up with a $200 blood test. And if cancer is detected early, the likelihood of a cure is high...
...clump together and vascular walls to begin to break down. In older patients, a lifetime of this damage may give arteries the scarred and thickened texture that provides circulating cholesterol with a place to stick and grow. In the young boy, accelerated homocysteine production caused by a genetic defect apparently led to accelerated damage. In both instances, however, McCully points to the same chemical culprit. "The underlying cause of heart disease," he says, "is an imbalance in the system that controls homocysteine levels...
